Pentax 8.5x21 U-Series Papilio II Binocular Description

The compact and lightweight 8.5x21 U-Series Papilio II Binocular combines aspherical optical elements and BAK4 Porro prisms to deliver edge-to-edge image sharpness with a 51° apparent angle of view. The optical elements are also fully multi-coated to provide a high transmission of light. With a 8.5x magnification and 21mm objectives, you obtain a notable magnification, insignificant image jitter due to unsteady hands, and a compact form factor. You can easily spot your targets with a wide 6° angular field of view and quickly bring them into focus with a center focus wheel. In addition to observing distant scenes, birds, and game, the minimum focus of 20" allows you to study in detail close objects like butterflies, animal footprints, marks, or landscape features. To reduce image jitter while observing distant objects or for prolonged observations, you can connect the binocular to a tripod via an integrated 1/4"-20 socket. The binocular also features a 2.5mm exit pupil, a 15mm eye relief, and interpupillary distance and diopter adjustments.

The binocular is very compact, lightweight, and features a single piece frame that houses objectives, which allows for a synchronized interpupillary adjustment. To accommodate eyeglasses wearers, the binocular offers twist-up rubber eyecups. Also included are a carrying case, a neck strap, and eyepiece covers.

The Papilio is a unique binocular. Of course it’s a fine and compact companion on nature trails and holidays, but when your interests are flowers, insects, bugs or butterflies the Papilio turns out to be an indispensable instrument. No other binocular combines fine handling and easy viewing with an unsurpassed close focus of only 50cm! You can observe nature in its natural habitat without disturbing or missing the finest detail.

New Fully-multi-coated optics
Fully multi-coated lenses serve the essential purpose of maximizing the amount of light passing through a lens, thereby prevent flare and ghosting from interfering with your view. PENTAX applies multiple layers of coatings to every surface of every element and prism in the full Sport Optics line-up. These fully-multi-coated optics assure the maximum light transmission resulting in a clear, crisp view of the world.

BaK4 prisms
Due to its outstanding refractive index, the BaK4 glass prism found in all PENTAX sport Optics is highly acclaimed for its perfectly round exit pupil and clear, unvignetted image.

Aspherical lens elements
Edge-to-edge sharpness is a vital element to comfortable viewing. To achieve this, we utilise aspherical lens elements in our eyepieces. This is a specially shaped lens design that reduces aberration to a minimum.
